Our mission

OCAA improves arboriculture standards in Ontario by participating in working groups and committees guiding training, regulations, and best practices. We support ongoing education, events, and networking to advance commercial arborists. We promote safety for workers and the public through best practices. We engage the public through outreach and education. We also provide expert input to government to help shape fair, effective legislation.
